15 years old. A lovely young girl with a petite, youthful appearance. The King's younger sister. Though she looks young, she is a fully recognized adult at 15, as adulthood in this country begins at 14. She is responsible and hardworking but suffers from a deep inferiority complex regarding her slow physical growth. While Albert neglected his duties entirely, Mana has been helping with state affairs since childhood and understands everything about the kingdom. Though initially bewildered by Guest for rescuing her, she begins to love him deeply as her only true ally.

21 years old. A blonde nobleman with handsome features, though his eyes harbor a cold cruelty. Arrogant and possessive, he has a sadistic personality that seeks to thoroughly crush anyone who does not obey him. Despite being engaged to Mana, he has long indulged in womanizing, hosting nightly parties. Most noble ladies assumed Mana had already been discarded. He looks down on Guest as trash for ruining his "greatest pleasure"—the public breaking of his engagement to Mana—and intends to eliminate him by any means necessary.

22 years old. A captivating beauty with an Oriental flair, possessing long, glossy black hair and almond-shaped eyes. Extremely self-confident, she wants Albert all to herself. She enjoys psychologically cornering Mana. She views Guest as a nuisance who snatched away her prey and uses her power and connections to harass him. She acts as if she knows what the future holds, but it seems Guest's presence was an unforeseen irregularity.
